Q: Why is TSC recommending the Mighty Mule 12V 7Ah Automatic Gate Opener Battery in the "get everything you need" section if the specifications of this model (MM371W) say it isn't compatible with it? What am I missing?

6 months ago
2 Answers
  • MightyMuleSupport
    A: The Mighty Mule 12V 7Ah battery is compatible when used with the Mighty Mule Battery Enclosure Kit (part # MMB200). While the gate opener requires a 12-Volt battery for operation, the enclosure kit allows you to use this specific battery model as an alternative to a larger automotive or marine type battery.

Q: Is this compatible with the 500 series box

7 months ago
1 Answer
  • A: The Mighty Mule MM371W is unfortunately not compatible with the older 500 series control box because they use completely different internal logic boards and power configurations. While the external plastic boxes might look similar, the newer "Smart" technology in the MM371W requires its own specific control board to function correctly.

Great gate opener with bad instructions

6 years ago
This gate works great and is easy to install once you know what you need to do. The instructions skip some key steps to get the gate to properly open/close. You must have two power sources, the battery and the solar OR run a line you can plug in. Even if you have a fully charged battery the gate will not open. The circuit loop needs to be complete. You'll need this set up before you attach the arm to the gate because the motor has to extend the arm out, don't do it by hand. Also, the instructions for how to set the gate arm is incorrect. You must press and hold until you hear a beep to set the gate. The instruction say press and release. Press and hold is also the previous step, so hold and release are intentional, incorrect wording. If we have to do another gate, it would be really quick, so I would buy this again.

Most Helpful Critical Review

Buy Some Other Gate Opener - Not this one

3 years ago
Ok, so let's start with how much you will be spending on a gate and opener. Buying a 6X6 post, gate, Marine Deep Cycle battery, solar panel, and two remotes - you will be spending a chunk of money. So, if you were smart you would do some research on the product that you will need for a gate opener. Well, I am here to tell you to NOT BUY this product - and here is why. The gate opener is nothing more than a computer board, a "worm screw motor" and a limit switch. Out of all the parts, the limit switch is most likely to wear out first. Understand, this is not new technology, as it is the exact same that the LARGE satellite dishes used to move the dish. So lets look at the product and the quality. The limit switch is a small "toggle switch that tells the worm screw to stop when the gate is fully open. It is a $3 part. However, the way the Mighty Mule is designed, when this switch goes bad - you will be spending Hours trying to fix it - as Mighty Mule does not sell the "plug and play part" to replace the switch. The limit switch is supper cheap and rides on the screw part of the worm gear. It will be surprising if it lasts a year - ask me how I know. When the switch gets wore out or binded up, it will fail. The cheap part will not be available online or from Mighty Mule and you are going to have to Jerry Rig it to work. Yes, your purchase will be worthless without this part. My limit switch failed after one year. I took the part number and searched the internet - no luck. I went to Mighty Mule and it's sister company - no luck. I had to find a replacement on the internet- that matched up the with the existing size, drill out the old screws, attach it to the existing mount (good luck with that part) then attach the wires and reprogram the unit (numerous times) to get it to work. Most people today do not have the mind set to fix the #$%# part and will go buy another gate opener. This is why I suggest you look at other gate openers online and pass on buying this one. This unit is the perfect example of "PLANNED OBSOLENCE" . Not good quality and you will not be able to buy the "plug and play" part to fix it.

NOT long lasting!

Circuit board replacement is about the same as the entire system! I’ve been through two of these gate openers in eight years and now I’m at the point where I’m questioning a pricy upgrade or just an understanding that I’ll need to replace the opener every four years…disappointing.

Yes, I recommend this product.

DLB Sorry you are having issues with your system! Please reach out to our tech support team about the bent arm. They can be reached at 1-800-543-1236 M-F 8am-7pm and Sat 10am-6pm EST. I am not sure if you are using a MMB200 Battery box with a FM150 Mighty Mule 12volt 7-amp hour battery. The MMB200 holds two FM150 batteries, and you may want to add an extra FM150 battery and FM316 Battery warmer for the colder times of the year. Mighty Mule FM123 10-Watt Solar panel can have another FM123 added to provide more solar power to recharge the batteries, or you could use our new FM125 30-watt solar panel. Please review these options when you call Tech Support!

Works when it wants too

This thing only works when it wants to. Sometimes it will open with the button and sometimes with the code, but most of the time it doesn't want to work at all. Very frustrating for the price we paid with all the extra remotes, keypads, etc for it to not work 99% of the time.
